Question

I need someone to check this question for me.


I solved the system using elimination
3x-9=3
6x-3y=-24


3x-9y=3
18x-9y = -72
= -15x-0=75
x= -5





6x-3y=-24
6(-5)-3y=-24
-30-3y=-24
y=-2

Answer 1

Perfect.:)

Answer 2

\[3x-9y=3\]\[6x-3y=-24\]
is \((x,y)=(-5,-2)\) a solution?

does
\(3(-5)-9(-2)=3\)?
and
\[6(-5)-3(-2)=-24\]?

Answer 3

Thank you for checking it for me :)

Answer 4
